Problems solved by technology

The color, fragrance and taste are all good, comparable to "Songjiang perch". At present, the outstanding problems are the increase of breeding diseases, irregular drug use, and even a few units abuse illegal drugs, so that unqualified commercial fish appear on the market.
Quality and safety problems caused by excessive drug residues in aquatic products have become a bottleneck restricting production and sales. There is an urgent need for a scientific and precise artificial breeding method for four-gill perch in the market.

Embodiment 1

[0012] A scientific and precise four-gill perch artificial breeding method comprises the following steps:

[0013] Cultivation facilities: square pond with flat bottom, less silt, convenient drainage and irrigation, with an area of ​​about 166 m2 and an average water depth of 0.8 m. Ten days before the fish species are put into the pond, they are disinfected with 10 mg / L strong chlorine. Keep the water quality lean, with a pH of 7.8, fewer types and quantities of zooplankton, and aquatic plants growing around the pond. The pond is equipped with a water purification system, including coral stone, filter cotton, activated carbon, etc. Use micro-pumps to circulate the water, which can not only purify the water quality but also increase the dissolved oxygen in the water body, so as to achieve the purpose of keeping the water quality fresh for a long time. Put some tiles or stones at the bottom of the tank, keep the water temperature at 26 ℃ ~ 28 ℃, and the pH at 6 . 5~7. 5, diss...

Embodiment 2

[0019] The preparation method is the same as in Example 1.

[0020] In the juvenile stage of the four-gilled perch of growth, pull out, divide into the middle of five ponds, 300 in every pond, throw in the microbial four-gilled perch of the embodiment of the present invention 1 respectively in the four ponds according to the dosage of 200kg per mu fat and common fourgill perch fat (control 1, from Beijing Century Arms Biotechnology Co., Ltd. ), the other pond did not put in four-gill perch fertilizer (comparison 2), but put in the same amount of common fish food, the rest of the feeding amount was the same, and the cultivation environment was the same. After 2-4 months of cultivation in Example 1, compared with other Yield and growth status of four-gill perch are specifically shown in Table 1 and Table 2:

[0021]

[0022]

[0023] Through the comparison of Table 1 and Table 2, it can be found that adding the compound microbial fertilizer of the presen...

Abstract

The invention discloses a scientific and precise artificial cultivation method for four-gill weever. The method comprises the following steps that a square pool is selected as the cultivation facility, the pool bottom is flat, less sludge exists in the pool, the pool is convenient in irrigation and drainage, and the average water depth of the pool is 0.8 m; ten days before seedlings are put into the pool, the pool is disinfected by trichloroisocyanuric acid with the concentration of 10 mg / L; compound microorganism fertilizer provided by the invention is added to promote the rapid growth of the four-gill weever, the content of EPA is increased, the four-gill weever diseases are reduced, the mortality rate due to diseases is reduced, and meanwhile, beneficial microorganisms in the water body are increased, and the final grade and quality are improved. When the scientific and precise artificial cultivation method is adopted to carry out scientized and detailed raising, the yield-increasing effect in short term is obvious, the survival rate is high, and the scientific and precise artificial cultivation method is applicable to industrial and large-scale development.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a scientific and precise four-gill perch artificial cultivation method. Background technique [0002] Special product of Xiangshui County, produced in the middle and lower reaches of the Guanhe River. The body of the fish is blue-gray, with black spots on both sides and dorsal fin. Because there is a deep fold on the gill cover, it looks like four gills, so it is named "four-gilled perch". Commonly, each piece is about 3-5 catties, and the larger ones can reach dozens of catties. Every year around the "grain of ear" is the fattest season for sea bass. In the Bailiguan River, fishing boats compete and set up nets to fish. At this time, Xiangshui, Shuanggang, Chengang and other places can be seen at any time on the market. The meat of four-gill perch is white and tender. After cooking, the meat is like garlic cloves. The soup is milky white, thick and sticky, and the fragrance is like s...
